SPECIFICATION forming part Of Letters Patent NO. 728,406, dated May 19, 1 903.

Application filed July 16, 1902. Serial No. 115,847. (No model.)

To otZZ whom it may concern:

Be it knownthat I, OSCAR G. NICKERSON, a citizen of the United States, residing at Ohatham, in the county of Barnstable and State of Massachusetts, have invented certain new and useful Improvements in Lumber- Wagons; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lumber-wagons; and it consists in the novel construction and combination of the parts, hereinafter fully de-' scribed and claimed.

In the drawings, Figure 1 is aside view of the wagon with the wheels removed. Fig. 2 is a plan view of the wagon. Fig. 3 is a crosssectionthrough the tongues. y

A is the rear axle, provided with wheels at in the usual manner.

Bis a bolster, and C is the front axle, provided with wheels 0 and pivoted under the bolster in any approved way. I

D is the draft-pole, which is secured to the front axle.

The bolster B is provided with guards d.

to prevent the lumber from slipping sidewise ofi it.

E is a tongue secured to the rearaxle A and strengthened by inclined braces e.

F is a tongue secured to the bolster B and arranged to slide over the tongue E.

G G are two guide-straps for the slidable;

tongue F. These straps are secured to the tonguesE and F, and one of them, G, is provided witha rollerf at its upper part for the tongue F to bear against.

The rear axle is provided with guards g to prevent the lumber from sliding sidewise oft it, and h is a roller journaled between the guards g. The lumber rests on the said roller h and the bolster. One ofthe guards g has an inclined side surface '01, and 7' is a fasten ing wedge or plate which is pivoted to the lower part of the said guard. The wedgeshaped plate is provided with a pin j for securing it to the guard, and the lumber fits tightly between this plate j and the opposite guard.

The slidable tongue F is provided witha 36-. ries of holes 70, and K is a pin which engages with a hole in the lower tongue E and with either of the holes k.

When the lumber on the wagon is to be unloaded, the rear wheels at are locked, and the pin K is removed. The locking-plate j is pulled out, so as to free the lumber, and the horses are backed. The lumber slides over the roller h until its center of gravity passes over it. The lumber then tilts up until its rear end rests on the ground. *The peculiar construction of the tongueguides and the use of the roller f permits the tongues. to slide while the load is on the wagon without greatresist-ance, so that thelumber may be unloaded,ashereinbeforedescribed. The rear wheels are then unlocked, and the wagon is, drawn forward from under the lumber, which is unloaded onto the ground in-this manner 1 very quickly and without manual labor.

What I claim is' 1. The combination, with a rear axle provided with a tongue E, and a front-axle bolster provided with a tongue F which slides above the tongue E; of a guide G secured to the free end of the upper tongue F and engaging with the lower tongue 'E, aforked guide G secured-to the lower tongue and straddling the upper tongue F, a roller journaled in the forked guide Gr and bearing against the upper side of the tongue F, and means for connecting the said tongues together, substantially as set forth. 2. In a lumber-wagon, the combination, witha rear axle provided with a longitudinal tongue, a guide secured to the said tongue,

guards projecting fromthe said axle, a wedge- I shaped locking-plate pivoted to the said axle and securing the lumber between the guards, a roller journaled between the said guards,' and a roller journaled in the upper part of the said guide; of a front-axle bolster pro-
